A down-market is defined as those periods (months or quarters) in which named index return is less than 0. In essence, it tells you what percentage of the down-market was captured by the manager. For example, if the ratio is 110%, the manager has captured 110% of the down-market and therefore underperformed the market on the downside.

Upside capture ratio measures a manager's performance in up markets relative to the named index itself. It is calculated by taking the security's upside capture return and dividing it by the benchmark's upside capture return.
